Beschreibung
Zusammenfassung:	A vane pump or motor assembly includes a housing having an inner cavity with an inner wall disposed about a first central axis. A rotor is disposed in the inner cavity and is rotatable about a second axis that is offset from the first axis to create a variable width space between the rotor and the inner wall. plurality of vanes are moveably carried by the rotor and engage the inner wall to partition the variable width space into a plurality of chambers of increasing and decreasing volume in response to rotating the rotor. Each vane is in the form of a leaf vane having a mounting end formed with a hook portion and wherein the rotor includes corresponding recesses with latch portions that engage of each respective hook portion and supports the leaf vanes for outward swinging movement relative to the rotor for engaging the inner wall of the inner cavity.
